The all new Hushpro RF2 especially engineered for the 17HMR to eliminate the harsh propellant crack (less that a 22 firing subs). This is a clean sheet of paper project, using technologies both very old and cutting edge. Design work was done with the latest CAD systems. The core is "lost wax - investment cast" first used in the Bronze Age and then CNC machined. This means that the inner is all one piece, no separate springs and baffles. Total length 200mm with 50% overbarrel. Weight 255g (9oz) Pic with rule indicates the amount of barrel extension. Fits Maximum muzzle end diameter 17mm. Comes with camo sleeve as shown.

Special!! Barrel threading for only $50 with silencer purchase. Includes thread protector. Rifle and scope are only for illustration and are not included in the auction. Money back if it is not the best 17HMR silencer you have ever used. My feedback is my salesman!
